"J.D. Salinger spent 10 years writing The Catcher in the Rye and the rest of his life regretting it," according to a new book about one of America's best-known and most revered writers.

Salinger died three years ago at the age of 91, after publishing four slim books. But Catcher in the Rye has sold more than 65 million copies and has become a touchstone for young people coming of age around the world. It still sells hundreds of thousands of copies every year.

A stream of fiction and stories written by reclusive author J.D. Salinger will be published between 2015 and 2020, according to a new biography about the writer of The Catcher in the Rye, who died in 2010. Some of the books will reportedly revisit beloved Salinger characters such as Holden Caulfield.

The claims come from David Shields and Shane Salerno, co-authors of the biography Salinger, which will be published next week. Days later, Salerno's documentary film of the same name will be released (and in January, it will air on PBS).
